According to my research, Friction is bad when you get blisters that's when it can be harmful.
The answer should be transform
No, I heavier object will fall much faster than something lighter than it. This is because it’s more dense and hard so it can cut through the air particles quicker than a lighter object which takes longer to cut through the air and fall
Example:
A rock vs a feather
The rock will fall quicker because it’s more dense and falls straight down and the feather will be slower because it flows slowly down through the air particles
Answer: (A) "X: May use LF, HF, and UHF waves
Y: Travels at the speed of light
Z: May use MF and VHF waves"
1/total = 1/2 + 1/4 + 1/6
That means 1/total = 11/12
Which means total resistance = 12/11 or 1.09ohm
